售價(jià)較高同種規(guī)格的V錐流量計(jì)的價(jià)格要高于孔板流量計(jì),但低于可更換孔板流量計(jì)。由于V錐的用料多、加工工藝復(fù)雜、標(biāo)定費(fèi)用高,使得其售價(jià)較高。但是在考慮流量計(jì)時(shí),初次購(gòu)買價(jià)及安裝費(fèi)用、儀表的可靠性、長(zhǎng)期維護(hù)費(fèi)用、長(zhǎng)久壓力損失等綜合因素的總評(píng)才是選取流量計(jì)的依據(jù),只有綜合考慮并權(quán)衡了以上這些重要因素,才能做到合理選型，山西液體渦輪流量計(jì)廠家直供。如前所述,V錐流量計(jì)除了在初次購(gòu)買費(fèi)用上高于孔板流量計(jì)外,其他的費(fèi)用應(yīng)該與孔板流量計(jì)持平或低于孔板流量計(jì)。尤其是在補(bǔ)償壓力損失所需要的耗能方面,V錐流量計(jì)遠(yuǎn)遠(yuǎn)優(yōu)于孔板流量計(jì)。所以從長(zhǎng)遠(yuǎn)考慮,使用V錐流量計(jì)的綜合費(fèi)用要低于孔板流量計(jì)。使用可更換孔板的目的就是為了提高孔板的量程比。但是其價(jià)格昂貴。如果給V錐流量計(jì)配兩臺(tái)不同量程的變送器（壓力變送器、差壓變送器）,那么其量程比的擴(kuò)展要遠(yuǎn)大于可更換孔板流量計(jì),而其價(jià)格要遠(yuǎn)低于可更換孔板。3差壓較低由于V錐流量計(jì)的流出系數(shù)要大于孔板流量計(jì)的流出系數(shù),使得相同流量時(shí)孔板的差壓值要高于V錐的差壓值?？装辶髁坑?jì)的變送器一般都是用中差壓表,V錐流量計(jì)一般用低差壓表，山西液體渦輪流量計(jì)廠家直供。

長(zhǎng)期以來(lái),孔板流量計(jì)由于其技術(shù)成熟、標(biāo)準(zhǔn)化程度高、結(jié)構(gòu)簡(jiǎn)單、維護(hù)方便等特點(diǎn)而被地應(yīng)用。在海洋石油工程中也常常會(huì)用到孔板流量計(jì)。以采油平臺(tái)的測(cè)試分離器氣體出口測(cè)量為例,由于該介質(zhì)為氣體,一般壓力較高,介質(zhì)成分較復(fù)雜,流量范圍隨著年份變化較大等特點(diǎn),決定了該場(chǎng)合應(yīng)用孔板流量計(jì)為合適。尤其近年出現(xiàn)的可更換孔板更是解決了原有孔板流量計(jì)的低量程比的缺點(diǎn)而被地應(yīng)用。但是可更換的孔板價(jià)格昂貴,一般至少為同管徑孔板流量計(jì)價(jià)格的5倍以上。那么有沒(méi)有更好的產(chǎn)品來(lái)代替它,我們認(rèn)為V錐流量計(jì)就是代替它的優(yōu)先產(chǎn)品。
